Why is a portion of the lower sideband of the AM picture signal transmitted along with the
carrier and full USB ? Does it need any correction somewhere in the television link ? If so where
is it carried out ?

Answer / kamali
This happens in case of your vestigal side band modulation.(VSB).Here a part of upper side band is transmitted and to compensate for that,a part of LSB is also transmitted.Because,the frequencies near that range are most of the video signals..hence ,we prefer VSB for television transmission..
